Does the using statement dispose only the first variable it create?

Question

Let\'s say I have a disposable object MyDisposable whom take as a constructor parameter another disposable object.

using(MyDisposable myDisposab         


        

Answer 1

Why not nest them?

using(var outer = new AnotherDisposable())
{
   using(var inner = new MyDisposable(outer))
   {
      //whatever
   }

}

Now at least you can be sure they'll be disposed off correctly.
